Can RAM cause blue screen?

The RAM is one of the most likely factors to trigger a blue screen in Windows. Problems with a single module could cause BSOD errors and even lead to programs crashing. Experts recommend using Memtest86+, an open-source tool, to identify and fix issues with the RAM.

To identify if the RAM is causing the blue screen, you will have to observe what triggers it. If the BSOD appears after launching a specific program or app, that’s probably the culprit. But, if the PC’s performance is affected, and you experience random BSODs, the RAM could be to blame.

Can Windows 11 cause BSoD?

After installing the Insider build version of the Windows 11 OS in the beginning, many users have been facing different issues, including the BSoD error.

With the launch of Windows 11, Microsoft renamed it the Black Screen of Death instead of the usual Blue Screen of Death.

However, Microsoft soon changed the screen color to blue when the PC fails to boot up or when there’s a stop error, as in previous versions of Windows.

The Black Screen of Death error message may usually appear after connecting a new piece of hardware like a USB drive, graphics adapter, etc.

In some cases, you may also encounter TCPIP.sys BSoD error on Windows 11 due to a third-party antivirus, and hence, disabling the software could help fix the issue.

However, if you encounter any other Black Screen of Death on your PC, let us know in the comments box below.
